Definitions

  • the disclosure relates to durable and scratch resistant anti-reflective articles and methods for making the same, and more particularly to articles with multi-layer anti- reflective coatings exhibiting abrasion resistance, scratch resistance, low reflectivity, and colorless transmittance and/or reflectance.
  • Cover articles are often used to protect critical devices within electronic products, to provide a user interface for input and/or display, and/or many other functions. Such products include mobile devices, such as smart phones, mp3 players and computer tablets. Cover articles also include architectural articles, transportation articles (e.g., articles used in automotive applications, trains, aircraft, sea craft, etc.), appliance articles, or any article that requires some transparency, scratch-resistance, abrasion resistance or a combination thereof. These applications often demand scratch-resistance and strong optical performance characteristics, in terms of maximum light transmittance and minimum reflectance.
  • some cover applications require that the color exhibited or perceived, in reflection and/or transmission, does not change appreciably as the viewing angle is changed. In display applications, this is because, if the color in reflection or transmission changes with viewing angle to an appreciable degree, the user of the product will perceive a change in color or brightness of the display, which can diminish the perceived quality of the display. In other applications, changes in color may negatively impact the aesthetic requirements or other functional requirements.
  • optical filters are often made from multilayer coatings having differing refractive indices and made from optically transparent dielectric l material (e.g., oxides, nitrides, and fluorides). Most of the typical oxides used for such optical filters are wide band-gap materials, which do not have the requisite mechanical properties, such as hardness, for use in mobile devices, architectural articles, transportation articles or appliance articles. Nitrides and diamond-like coatings may exhibit high hardness values but such materials do not exhibit the transmittance needed for such applications.
  • Abrasion damage can include reciprocating sliding contact from counter face objects (e.g., fingers).
  • abrasion damage can generate heat, which can degrade chemical bonds in the film materials and cause flaking and other types of damage to the cover glass. Since abrasion damage is often experienced over a longer term than the single events that cause scratches, the coating materials disposed experiencing abrasion damage can also oxidize, which further degrades the durability of the coating.
  • Known anti-reflective coatings are also susceptible to scratch damage and, often, even more susceptible to scratch damage than the underlying substrates on which such coatings are disposed.
  • a significant portion of such scratch damage includes microductile scratches, which typically include a single groove in a material having extended length and with depths in the range from about 100 nm to about 500 nm.
  • Microductile scratches may be accompanied by other types of visible damage, such as subsurface cracking, frictive cracking, chipping and/or wear. Evidence suggests that a majority of such scratches and other visible damage is caused by sharp contact that occurs in a single contact event. Once a significant scratch appears on the cover substrate, the appearance of the article is degraded since the scratch causes an increase in light scattering, which may cause significant reduction in brightness, clarity and contrast of images on the display.
  • Single event scratch damage can be contrasted with abrasion damage.
  • Single event scratch damage is not caused by multiple contact events, such as reciprocating sliding contact from hard counter face objects (e.g., sand, gravel and sandpaper), nor does it typically generate heat, which can degrade chemical bonds in the film materials and cause flaking and other types of damage.
  • single event scratching typically does not cause oxidization or involve the same conditions that cause abrasion damage and therefore, the solutions often utilized to prevent abrasion damage may not also prevent scratches.

  • the measured hardness may appear to increase initially due to development of the plastic zone at shallow indentation depths and then increases and reaches a maximum value or plateau at deeper indentation depths. Thereafter, hardness begins to decrease at even deeper indentation depths due to the effect of the underlying substrate. Where a substrate having an increased hardness compared to the coating is utilized, the same effect can be seen; however, the hardness increases at deeper indentation depths due to the effect of the underlying substrate.
  • the indentation depth range and the hardness values at certain indentation depth range(s) can be selected to identify a particular hardness response of the optical film structures and layers thereof, described herein, without the effect of the underlying substrate.

  • Figure 9 illustrates the changes in measured hardness value as a function of indentation depth and thickness of a coating. As shown in Figure 9, the hardness measured at intermediate indentation depths (at which hardness approaches and is maintained at maximum levels) and at deeper indentation depths depends on the thickness of a material or layer.

Also, the optical coating of Example 13 was fabricated and tested. In Example 13 and Modeled Example 14 the optical coating included A10 x N y and S1O 2 layers, and a strengthened aluminosilicate glass substrate having a nominal composition of about 58 mol% Si0 2 , 17 mol% A1 2 0 3 , 17 mol% Na 2 0, 3 mol% MgO, 0.1 mol% SnO, and 6.5 mol% P 2 O 5 , prior to ion exchange with a K 2 0 bath, as shown in Tables 13 and 14.

  • the optical coatings of Example 15 have a balance of optical and mechanical properties. That is, these examples balance scratch resistance with good optical performance in terms of reflectance, color, and/or color shift. More specifically, these examples have a reflectance (over the optical wavelength regime) of about 6% to less than about 10% (and less than about 8% in some examples), and maintain good scratch resistance. Compared to optical coatings optimized for scratch resistance (which have a tradeoff of higher reflectance, i.e., about 10%), the coatings in these examples sacrifice a small amount of scratch resistance to desirably decrease reflectance (to a range of from about 6% to less than about 10%, and to less than about 8% in some examples).

  • hardness quickly increases within the first 100 nm from the surface (up to a value of about 17 to 20 GPa), and is maintained at about the same value (about 17 to 20 GPa) as depth increases from 100 nm to about 700 nm or about 800 nm, as measured from the surface.
  • Such a hardness profile is desirable in reducing damage from scratches, both more severe scratch events responsible for more visible scratches, and less severe scratch events that might otherwise affect the surface
  • the optical coatings of Examples 15 ' -17 have a balance of optical and mechanical properties. That is, these examples balance scratch resistance with good optical performance in terms of reflectance, color and/or color shift.
